The taxonomic position of unidentified group 6 of as described by Nakamura and Swezey (L. K. Nakamura and J. Swezey, Int. J. Syst. Bacteriol. 33:46–52, 1983) was determined, and the taxonomy of was reexamined. The results of PCR amplification of a 16S rRNA gene fragment with a specific primer and comparative analysis of 16S rRNA gene sequences warranted placing the two taxa in the genus . The levels of DNA reassociation among the strains revealed four groups (designated groups I, II, III, and 6), each with a high level of intragroup relatedness (>72%). Clustering based on pheno-typic characteristics correlated well with DNA relatedness grouping. strains were scattered in groups I, II, and III. Strains labeled the type strain of from different culture collections appeared in groups I and III. Strains found in group I were identified as sensu stricto, and the one strain found in group III was identified as . Group 6 encompassed strains formerly assigned to group 6, and group II contained other strains identified as . Groups 6 and II were phenotypically and genetically distinct taxa that were distinguishable from the previously described species. These findings showed that groups 6 and II were new species, for which we propose the names and , respectively.
